Abstract:
The invention relates to a process for the addition of HF to halogenated alkenes by reacting these with at least one hydrofluoride of the formula [B.cndot.n HF], in which B is an organic nitrogen base and n is an integer or fraction .ltoreq.4, it being intended that the reaction of perfluoroiso-butene CF.sub.2 =C(CF.sub.3).sub.2 is excluded.
